Yes. I would go back to heuristics. It doesn't matter how educated, sophisticated, or experienced we are; every one of us uses mental shortcuts to make political decisions.
Some research from the United States from a few years ago suggests that when it comes to, say, motivated reasoning and rationalization, we think we're making our own rational decisions, but we're really rationalizing. Low-information voters do it, but sophisticated voters sometimes do it as well. The difference is that they do it with ideology and a more sophisticated story. It is a problem that cuts across groups, although you are right that there is more susceptibility with lower-information voters.
What's interesting is that those folks often rely on their family or friends to get political signals. One of the interesting things about Facebook and Twitter is that people are getting a lot of information, but the stuff that seems to be having a huge impact is that their Uncle Larry posted this thing, and they trust and like him. He's a lot like them, so they're going to do this. Then a lot of those heuristics have moved to family and friends, especially on Facebook.
How do we start a virtuous cycle or a positive cycle in which the stuff people share is informed? When we talk about this stuff, we think of it as a demand and supply problem. There's a demand for nonsense and good information. There's a supply of nonsense and good information. How do we encourage the supply and demand to link up and for that information to be better?
Part of it is making sure the environment is filled on the supply side. We're going to supply-side epistemic economics here. The supply side is good stuff. You want as much good reliable information as you can get on the supply side to try to drown out and provide choice for those who want something better than fake news, misleading news, or tabloid trash.
